" In the cities of the Jewish diaspora (especially Alexandria, Antioch, Tarsus, Ephesus, and Rome), Jews were widely admired by their gentile neighbors. For one thing, they had a real religion, not a clutter of gods and goddesses and pro forma rituals that almost nobody took seriously anymore. They actually believed in their one God; and, imagine, they even set aside one day a week to pray to him and reflect on their lives. They possessed a dignified library of sacred books that they studied reverently as part of this weekly reflection and which, if more than a little odd in their Greek translation, seemed to point toward a consistent worldview. Besides their religious seriousness, Jews were unusual in a number of ways that caught the attention of gentiles. They were faithful spouses—no, really—who maintained strong families in which even grown children remained affectively attached and respectful to their parents. Despite Caesar Nero’s shining example, matricide was virtually unknown among them. Despite their growing economic success, they tended to be more scrupulous in business than non-Jews. And they were downright finicky when it came to taking human life, seeming to value even a slave’s or a plebeian’s life as much as anyone else’s. Perhaps in nothing did the gentiles find the Jews so admirable as in their acts of charity. Communities of urban Jews, in addition to opening synagogues, built welfare centers for aiding the poor, the miserable, the sick, the homebound, the imprisoned, and those, such as widows and orphans, who had no family to care for them. For all these reasons, the diaspora cities of the first century saw a marked increase in gentile initiates to Judaism. Many of these were wellborn women who presided over substantial households and who had likely tried out some of the Eastern mystery cults before settling on Judaism. (Nero’s wife Poppea was almost certainly one of these, and probably the person responsible for instructing Nero in the subtle difference between Christians and more traditional Jews, which he would otherwise scarcely have been aware of.) These gentiles did not, generally speaking, go all the way. Because they tended to draw the line at circumcision, they were not considered complete Jews. They were, rather, noachides, or God-fearers, gentiles who remained gentiles while keeping the Sabbath and many of the Jewish dietary restrictions and coming to put their trust in the one God of the Jews. Pilgrimage to Jerusalem, however, could turn out to be a difficult test of the commitment of the noachides. For here in the heart of the Jewish world, they encountered Judaism enragé, a provincial religion concerned only with itself, and ages apart from the rational, tolerant Judaism of the diaspora.
